A boy wants use his slingshot to shoot a water balloon into the air. His
slingshot has a spring constant of 50 N/m, and he pulls it back 1.5 m before
releasing the water balloon and launching it into the air. If air resistance can
be ignored and the water balloon has a mass of 1.5 kg, what is the
approximate maximum height that the water balloon can reach? (Recall that g
= 9.8 m/s²)
A. 4.6 m
B. 2.1 m
OC. 0.7 m
D. 3.8 m

A spring is used to launch a coffee mug. The 20cm long spring can be compressed by a maximum of 8cm. The mug has a mass of 700 g. What kind of spring do you need to launch the mug at least 2 stories high (5 m) - as measured from the relaxed spring position - using the maximum compression? N/m
A box of mass m = 0.31 kg is set against a spring with a spring constant of k1 = 549 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 444 N/m. a.) How far d2, in meters, will the second spring compress when the box runs into it? b.) How fast v, in meters per second, will the box be moving when it strikes the second spring? c.) Now assume friction is present on the surface in between the ends of the springs at their equilibrium lengths, and the coefficient of kinetic friction is μk = 0.5. If the distance between the springs is x = 1 m, how far d2, in meters, will the second spring now compress?
